PhD in Natural Language Processing

CLCG, University of Groningen

Welcome to my website! 👋 I am a PhD student in the InCLoW team within the Natural Language Processing group (GroNLP 🐮) at the University of Groningen. I’m also a member of the InDeep consortium, working on user-centric interpretability for generative language models. My supervisors are Arianna Bisazza, Malvina Nissim and Grzegorz Chrupała.

Previously, I was a applied scientist intern at Amazon Translate NYC, a research scientist at Aindo, and a Data Science MSc student at the University of Trieste, where I helped found the AI Student Society.

My research aims to translate theoretical advances in language models interpretability into actionable insights for improving trustworthiness and human-AI collaboration. To this end, I lead the development of open-source interpretability software projects to enable reproducible analyses of model behaviors. I am also excited about the potential of human behavioral signals such as keylogging, gaze and brain recordings to improve the usability and personalization of AI solutions.

Your (anonymous) constructive feedback is always welcome! 🙂
